Energy Usage
How much energy your Western Visayas home uses daily directly impacts the solar system size you'll need. Whilst typical Western Visayas households consume 7 kWh daily, homes with good insulation and modern appliances often use far less energy.
Future-proofing is worth considering: if you plan to add an EV, heat pump, or pool, your energy needs may grow — and sizing your solar system a little larger now can save money later.
Typical energy usage per person per day in Western Visayas:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
Most solar installers in Western Visayas would recommend starting at around 1.8kW for a household using 7 kWh per day, with room to go larger if budget allows. We recommend sizing between 2.8kW and 3.7kW for optimal results as solar output fluctuates daily and seasonally.
While December is the weakest month for solar in Western Visayas, September more than makes up for it — and a battery can help bridge the gap between seasonal highs and lows.
Solar & Energy Savings
Calculate Heat Pump & EV Savings
Electrify your home by replacing gas heating, petrol vehicles, and other fossil fuel appliances with electric alternatives powered by clean solar energy. This delivers significant additional financial savings and substantial carbon emission reductions. Our calculator helps you compare costs and model the financial impact of switching to electric appliances and vehicles.
How Solar Reduces Your Electricity Bills
The calculations below show how your electricity bills change with solar. Your Old Bill of - per month (- annually) is calculated from your total energy consumption multiplied by the grid electricity rate. Your New Bill of - per month (- annually) accounts for solar generation, the percentage you use directly (self-consumption), remaining grid consumption, and feed-in credits for excess energy exported to the grid. This results in monthly savings of - (- annually).
Battery Storage Western Visayas
Solar Battery Sizing
A 2.8 kW solar-only setup in Western Visayas delivers around 50% self-sufficiency, leaving 50% dependent on grid electricity. The jump from 50% to 99% self-sufficiency with a 10 kWh battery is most noticeable on your evening electricity bills, when rates are often highest.

Solar & Battery System Cost Western Visayas
Understanding Solar & Battery System Costs
A 2.8 kW solar system at approximately ₱157,639 in Western Visayas can pay for itself through reduced electricity bills — often in under 6.4 years. Most solar-only systems reach payback in approximately 6.4 years, though battery storage lengthens payback periods whilst substantially boosting energy independence.
Whether you choose solar-only at ₱157,639 or add a battery at ₱486,817, the investment is typically recovered well within the system's 25-year lifespan.
